Lead study investigator Timothy J. Whelan, BM, BCh, professor of Oncology and the division head of Radiation Oncology at McMaster University and the Juravinski Cancer Centre, Hamilton, Ontario, explains that the results from his NCIC-CTG MA.20 intergroup phase III trial demonstrated that women with breast cancer that have 1-3 positives nodes after breast conserving surgery, usually receiving whole breast irradiation, will benefit from the addition of regional radiation to their treatment.

Lead study investigator Timothy J. Whelan, BM, BCh, professor of Oncology and the division head of Radiation Oncology at McMaster University and the Juravinski Cancer Centre, Hamilton, Ontario, discusses the amount of women, by percent, that might benefit from the results of the NCIC-CTG MA.20 intergroup phase III trial for women with breast conserving surgery that usually receive whole breast irradiation.

Dr. Whelan says on average at least 50%, or perhaps even higher, have breast conserving surgery. Not all of those will be node positive.

Lead study investigator Timothy J. Whelan, BM, BCh, professor of Oncology and the division head of Radiation Oncology at McMaster University and the Juravinski Cancer Centre, Hamilton, Ontario, discusses the various survival benefits found in the NCIC-CTG MA.20 intergroup phase III trial that randomized 1832 breast cancer patients to receive either whole-breast irradiation (WBI) or WBI plus regional nodal irradiation (RNI). Patients that received both RNI and WBI saw a disease-free survival of nearly 90% but failed to meet the primary endpoint of overall survival.
